Criticism of and inheritance from Husserl's phenomenology and Dilthey's philosophy of life are considered important sources of Heidegger's early humanology. From Husserl's phenomenology Heidegger inherits his methodology to form his own analysis of existence. As for the content of his studies he inherits Husserl's idea that “From the angle of phenomenology there is nothing else behind the phenomenon ”. The focus on individual of Heidegger's analysis conforms to Dilthey's idea that life refers to that of individuals. His exploration into temporal and historic features following this idea comes directly from Dilthey's idea that human life is a historic process.
